Micro Connectors 12-Pin to Dual 8-Pin PCIe GPU Extension Cable 300mm Black

SKU CH-G1YZ-VSDM2

Connects a 12-pin GPU to dual 8-pin power using 18AWG sleeved cable with combs, 300mm length, rated for 1300W supplies

  • ColorBlack
  • Designed for RTX 30 series cards with 12-Pin connectors
  • Compatible with RTX 3060, 3070 and 3080 models
  • 18AWG conductors with triple-layered sleeving for durability
  • 300mm length includes cable combs for tidy routing
  • Rated for power supplies up to 1300W

Purpose and fit

This cable converts a single 12-pin GPU connector into two standard 8-pin PCIe plugs, letting RTX 3060, 3070 or 3080 cards draw power from a conventional PSU. It is built for enthusiasts who want a tidy, sleeved extension rather than the stock adapter. Builders using an RTX 3090 should look elsewhere, as the wire gauge is not rated for that card.

Critical spec

The conductors are 18AWG copper, triple-layer sleeved and tested for power supplies up to 1300W, so the wire gauge is the figure that decides whether the cable matches your hardware. Each 8-pin branch uses the standard 4+4 pin layout, giving full compatibility with modular PSU cables.

Sustained behaviour

At 300mm the extension adds minimal resistance, keeping voltage drop low even when the GPU runs at full load for long periods. The flexible sleeve resists kinking and holds its shape, so airflow stays unobstructed and the routing remains clean after weeks of continuous operation.

Questions about this item

What does the 12-Pin connector mean for my RTX 3080?

It connects directly to the 12-Pin power socket found on RTX 3060, 3070 and 3080 cards, replacing the separate 8-Pin plugs that older cards use.

Does the PCIe 12-Pin interface limit the power my card can draw?

The cable uses 18AWG wires rated for supplies up to 1300W, so the 12-Pin link itself will not restrict a 3080 under normal loads.

How much room do I need behind the graphics card for the 300mm cable and combs?

The 300mm length plus included combs need roughly 30cm of clear space behind the 12-Pin socket to route cleanly without sharp bends.
